This is great for all ages. You just need a deck of card with numbers. If you’re using playing card remove the aces and face cards. You can use UNO or Racko cards. Put the cards face down in a pile. Take turns drawing 2 cards from the pile. Determine ahead of time if you will add, subtract or multiply the numbers on the 2 cards. The person to get the correct answer first, keeps the cards. The person with the most cards is the winner. You can also play where each person has a pile. Together each of you turn over one card. The first person to add, subtract or multiply the numbers correctly gets to keep the cards.
